POURING- LADLE.

Application filed. January G, 1922. Serial No. 527,455.

To frZZ whom t may concern.'

Be it known that we, ADoLPHn COLLIN and DIEUDONN JEUNEHOMME, subjects ot the King of Belgium,y residing', respectively, in Ougree, rue Champs du Mont, and `in Jemeppe sur Meuse, rue de la Station, Belgium, have invented certain new and useful Improvements in PouringyLadles; and we hereby declare the followingto he a full, clear, and exactdescription of the invention, reference ybeing made to the accompanying drawings, which form a part of this speci' lication.

The present invention has for its object to ohviate the disadvantages resulting from the actual means of tilting, in which the axis of the single worm wheel or the like, controlling the tilting, is horizontal. To this end the wheels or worms run in a protecting housing or box secured `onlyto a supporting arm of the ladle and on which is vertically guided the end of the trunnion of the ladle, or a part carried thereon, so that any movement ofthe geared transmission mechanism and any torsional y effort are prevented. Moreover in order to prevent the twisting of the wheels causing the seizing of the trunnions on their bearings, the toothed wheel mounted on the trunnion is actuated either by aworm or the like, the: axis of which is vertical, either by several worms or the like, the axisof which are parallel and `symmetrically adapted to the wheel.

Another object of the invention is the pro- `Vision of a complete lubrication of the train of gears controlling the wheel keyed upon the end ot' the trunnion supporting the ladle. For this' purpose the axes of these gears are inclined downwards andthe hub of the wheel. is provided with passages in which the lubricating oil is compelled to penetrate.

Another object of the invention consists in the production of a renewable air-interval between the ladle and its ring in order to reduce the getting 1 hot of the supportingl trunnion'and to suppress any cause oi e.\:- pension from the tilting mechanism.

In the accompanying drawings. Fig. 1 shows a ladle in section through the `axis ot suspension, on line A-B of Fig. 3; Fig. 2 is a detail of the end ofthe trunnion in section upon line C-D of Fig; Fig. 3 isa section upon line E--F of Fig. 1; Fig. 4; is an external view of the protecting box or housing;..Figs.j5 and 6 vare two construe tional modifications of the attachment of the protecting box or housing;l F igs. 7 to 11 show diii'erent positions of the controlling gear of the `wheel; Fig.- 12 is a section upon line G-H of F ig. 1. l

Upon the trunnion l secured to the lring 2 is keyed a .worm wheel 3 operated by an endless screw or worm 4;. The shaft 5 of this worm carries a bevel wheel 6 receiving motion from another bevel wheel 7 mountedv upon a shaft S operated from the exterior by a lever, a hand wheel or the like, lwhich engages, for example, with the squared end 9 of the shaft 8. y

The trunnion 1 rests upon a series of rollers or rolls 10 enclosed in a race-way such as 11 secured to the arm 12 of the ladle, the

said arm supporting by means of bolts the protecting box or housing 13 ot' the geared transmission mechanism. The end ot the trunnion 1 carries by means of rollers 141 a race 15 similarto the race 11. As shown in Figs. 2 and l. this race 15 is provided with arms 16 guided laterally 'and retained by parts 17 forming slidesand secured to the housing. ln this way, the housing is made independent from the ladle, so that the reactions oi.' the trunnions end have no influence on the housing and consequently `on the supporting arm, which suii'ers no torsional effort.

The hub of the wheel 3 is formed with a `series of holes 18, which as they Vcome in 'frontot corresponding holes 19 in the race 11, ensure the circulation ot oil carried by Athe arms 20 of the wheel 3 dipping into this oil.

`As shown in Fig. 1, the leverage pro-l ducing the zone a. ot torsion is very short, the effect is consequently minimized; this advantage is of greatest importance, because it thus reduces considerably a frequent cause oiy unsatisfactory operation of devices of l this kind.

Cil

(3, the axis of the endless screw or worm t is horizontal; as the plane ot reactions of this worm is perpendicular to the vertical plane ot the suspension arm l2, a binding of the trunnions on t-heir bearings may be caused. In order to prevent this disad- 'antage, the one or the other of the constructions represented in Figs. 8 to ll may be used.

As shown in Fig. T, the worm is vertical, whereby the reaction of this worm is no more in the horizontal direction, but in the direction ot' the vertical axis, consequently one cause of twisting is avoided, as the reaction otl the worm is in a vertical plane parallel to the vertical plane of the supporting arm. This vertical arrangement ot the worm 4 is theoretically the best, but in order to obtain an ample lubrication and to allow the worin to dip into an oil-bath, a suitable inclination downwards is given to the worm 1l, so that its axis and that of the arm meet each other under the trunnion l, as shown in Fig. 8.

For the purpose of' obtaining` a complete equilibrium of the system, and avoiding any cccei'rtricity ot the worm and any torsion olf the arms, it advantageous to replace the single worm ol" the precedent construction by two or more worms symetrically adapted upon the wheel mounted upon the trunnion and parallel two by two, so as shown in Figs. 9 and l0, where respectivelyv vertical and horizontal worms l and 4 actuate the same wheel 3. The worms et and el. are thus opposed one to the other in all positions in respect to the axis of the supporting arm. The torsional forces are thus combined and balanced.

The worms l and t are operated by a single transmission, spur gears or bevel gears, worm wheels or the like. For example in Fig. lO, on the shafts of the worms fl: and 4l. are secured spur gears 22 engagingwith a toothed gearing 23 mounted upon the shaft actuated by a hand wheel.

But, as in the case of the single vertical .worm ot' Fig. 7, the worms et and t are dillicult to be well lubricated, therefore the construction of Fig. ll is more practical, in which the two worms 4 and 4l engaging with the wheel 3 are inclinded downwards, so that their axes form an angle of about 90o. The shafts of these worms carry spiral gears 25 engaging` with a spiral gear 26 keyed upon a shaft 2T controlled directly or indirectly by a hand wheel. The whole mechanism is enclosed in a housing 28 secured solely to the arm 12 and dipping into an oil-bath. Furthermore a second support is not necessary for the trunnions carrying the worms t and il.

In this modilication a zone of torsion exists at the ends 29 ot the worms, while the ends 3() are balanced. In order to obviate this fault, the combination oit the two inclined worms is used with the sliding race l5, as represented in F l to 6.

The ring 2 (Figs. l and l2) is not directly secured against the ladle, but is in contact with the latter by means ot a series ol." wedges 32, or the like, riveted or bolted as in 31, so that an interval 33 exists between the ladle and the ring 2.

In this interval 33, as indicated by the arrows 34e, an air-current is obtained, maintaining the ring 2 and consequently its trunnions l at a low degree of temperature, and so preventing abnormal heating of these organs. The ascensional air-current indicated by the arrows 34 contact the ring 2 and thus favours its cooling, inasmuch as the conductibility is minimized and the radiation much attenuated.

Any 1isk of binding because of the raising of the temperature being avoided, the coetlicient of resistance of the organs may be raised. It will be seen that during the tilting ot the lilled ladle some cast-iron {iowing away along the ladle, will not remain upon the ring, which was thus submitted to a notable rising of temperature.

It will be evident that various modifications may be made in the construction and arrangement of theI various parts without departing from the spirit of the invention. or exceeding the scope ot the appended claims.
